Title: Method of farming laver using acid treatment agent
Inventor: KIM BYOUNG DAE
IPC: A01N63/10
Filed: 2019-09-03
Abstract: A laver culture method using an acid treatment agent according to an embodiment of the present invention comprises the steps of: attaching laver spores to a laver screen; producing a mixed solution in which an acid treatment agent and seawater are mixed; injecting the mixed solution into a container through which the laver screen will pass; coating the surface of the laver screen with the acid treatment agent in a procedure in which the laver screen passes through the container; and collecting laver attached to the laver screen. The acid treatment agent includes bacilli. According to the method of the present invention, an inorganic acid is not used for an acid treatment agent, and thus an inorganic acid remaining in laver or flowing into the sea is removed. Thus, the health of a consumer is not harmed, and it is possible to prevent ecosystem destruction and laver farm degradation. In addition, according to the present invention, by adding bacilli components to an existing acid treatment agent, which had insufficient prevention and treatment for laver disease, algae and diatoms are removed. Thus, a laver disease preventing and treating effect can be enhanced. Also, due to nutrients provided from bacilli, the growth of laver is promoted, and disease resistance is improved. Accordingly, efficiency of acid treatment can be improved by resolving a conventional problem in which efficiency is low in terms of an operation time and effects when only an organic acid is used instead of using an inorganic acid. In addition, according to the present invention, to relieve a problem of a conventional acid treatment agent which has not functioned properly at a post-type high temperature, bacilli activated even in a high temperature state are used. Therefore, even at a post-type high temperature, laver disease and fungus can be removed.
